IMPROVED HORSE-POWER.

The Schedule referred to in these LettersPateut and making part of the same.

To all whom 'it may concern:

Be it known that we, OYRUS' ROBERTS and J om A. THROP, of Three Rivers, in the county of St. J oseph, and State of Michigan, have invented certain new and useful Improvements in Horse-Poweraof which the following is a full, clear, and exact description, reference' being had to the accompanying drawings, which make part of this specification, and in Which- Figure-1 represents a plan or top view of our improved horse-power, in position for operation;

' Figure 2, a vertical longitudinal section of the same, at the line xa: of iig. l;

Figure 3, an end elevation of the same;

Figure 4, a vertical section of the bevel-wheel, at the line y y of iig. 1, showing its side roller; and

Figure '5, a view, in perspective, of the bearing for' the adjusting-bolt of one of the transverse braces.

The improvementsherein claimed consist- First, in arranging the bed-plate which carries the gearing of the horse-power atan angle upon the frame, in such manner, that when the `front wheels are vremoved, and the front end of the machine lowered upon the ground, the hed-plate shall be parallel thereto, and the gearing in proper position to beoperated by the horses. A

Second, in a novel arrangement and method of adjustment of the rollers which maintain the bevelwheel in position, whereby the same is kept truly in -linewith the pinion of the line-shaft, when in revoluthe front axle andwheels are removed, and the front end of the machine, which is provided with a transverse bolster, A3, lowered upon the ground, as shown in the drawings. A

The red lines in g. 2 show the machine in position for transportation.

An annular metallic bed-plate, O, which carries thev gearing by which the horse-power is driven, is secured to sills a upon the frame, above and contiguous-to the rear axle A2. Y l

The upper surfaces of the sills a are inclined at such au angle to the frame A, that when the iront end of the same is lowered upon the ground, the top of the bed-plate will be parallel thereto,"aud the gearing will consequently be in proper position to .be operated by the horses.

The gearing of the horse-power, not'being embraced in the improvements herein claimed, is not shown, with the exception of a central dished bevel-wheel, E, which gears, withv a pinion, d', upon a longitudinal line-shalt,

D, which is mounted in a bearing at the front end of Couplings D' are secured to each end of the lineshaft, to one or both of which, tumbling-rods may be connected. l By this arrangement, the tumbling-rod, which is connected -to the V'ont end of the line-shaft, maybe brought very near the ground, so that the horses can walk over it conveniently, and the line-shaft is in proper position for theA connection to be made, as soon as the front end of the machine is lowered uponthe ground.. I, v Y In order to prevent the bevel-wheel E from sagging or getting out of line when in operation, friction-rollers e c are arranged upon its upper surface, the one,

e, at a point immediately above the bevel-pinion d, and c the other, e4, ,at light angles to it, or nearly so. y l The friction-roller e revolves on a journal upon the lower end of an arm, el, w ich passes through a slot in a brace, e2, secured to the top of the Abed-plate (l, being made fast by a set-screw, e, thus rendering the roller adjustable for wear or for diierent heights of the bevel-wheel. The roller c4 rotates upon a journal at the free en of a swinging arm, e5, pivoted on a pin, ea, on the inside of vthe bed-plate, and is allowed to lise `and fall within properI limits, to follow the rocking of the bevelwheel, its range of motion being regulated by a pin, e7,- which can be inserted in any one of a series of holes in a standard, es, secured to the bed-plate or to the transverse brace thereof.

By this arrangement of the adjustable rollers, the

bevel-wheel is maintained truly inline with the pinion of the line-shaft, while at the same time a-sujiicient amount of lateral oscillationis permitted to prevent straining or binding. v

A name, F, is hinged to the rear end of the machine, which, when turned down and locked in positionemploy transverse braces G G', which'can be adjusted-A to suit uncvenness of the ground, in the following manner:

The upper ends of thebraces G G' are pvoted to pins g, upon the ends of brackets projecting rearward from each side of the frameA.

The braces G G', extending in opposite directions, transversely to the machine, rest upon the ground, their ends bearing against stakes driven firmly therein.

Slots gl are formed in the braces, near the point at which they cross each other, through which a bolt, g2, passes, having a nut, g, upon its rear end, by which the two braces may be clamped together, the end of the brace G being first adjusted to conform to any difference of lev'el in the ground, as shown in red and black lines in iig. 3.

A plate, H, is secured to the lower side of the bracket ofthe pin g, on the opposite side of the frame to the pivoted end of the brace G.

A slot, h, is formed in the plate H, having a series of recesses at its side, in any one of which may be placed a bolt, h', which passes through a slot in the brace G, and, having a nut upon its rear end, clamps thebrace to the plate at any desired height.

By this arrangement, it will be seen that the braces 4 G G are rendered adjustable, to conform to variations of level in the ground.

' he brace G may be made fast to the plate H, and

the brace G' moved upon it, or both moved together, as required.

What we claim as new, and desire to secure by Letters Patent, is-

1. The combination of the frame, the longitudinal line-shaft, and the inclined bed-plate, all constructed and arranged substantially as set forth, for joint operation.

2. The combination, with the bevel-wheel, of the adjustable friction-roller, arranged above the bevelpinion and line-shaft, and the adjustable side-roller, as constructed and arranged for joint operation, as set forth. j

3. The combination, with the bevel-wheel E, of the yvibrating friction-roller e4 and adjustable stop, as set forth. 1

4. The combination of the`hinged ame F, rod j; and catch f', with the frame of a four-wheeled horsepower, so arranged as tol-rest upon two wheels when in operation, substantially as set forth.

5. The adjustable transverse braces G G', for secur ing the machine in position when in operation, substantially as described, constructed, and arranged.
